SPRAY ELEMENT.

Specification of Letters Patent.

Patented Dec. 14, 1920.

Application filed November 12, 1918. Serial No. 262,206.

To all whom it may concern:

Be it known that I, J HARRY LAKIN, a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented new and useful Improvements in Spray Elements, of which the following is a specification.

This invention relates to a spray element and more particularly to a spray element used in conjunction with a nozzle and has for its primary object to provide a spray element of an inexpensive substantial construction capable of giving a whirling action to a liquid before making its exit from the nozzle.

An object of the invention is to provide a nozzle element of a construction that, in

,a very inexpensive manner, the capacity of the whirling liquid discharge can be changed. 1

Besides the above my invention is distinguished in the novel manner of shaping {the device so that the same may be readily cast and easily removed from the mold.

With these and other objects in view the invention will be better understood from the following detailed description taken in connection with the accompanying drawing wherein:

Figure 1 is a top plan view of the element shown associated with a cylindrical casing.

Fig. 2 is a side elevation of the device the casing being shown in longitudinal sec tion.

Fig. 8 is a vertical sectional view.

Fig. 4 is a sectional view through a slight modification of my invention.

Fig. 5 is a detailed view of a modified form of the projection.

Fig. 6 is an underneath view of the spray element.

My invention in one of its forms as shown in the drawing consists of a cylindrical body adapted to tightly fit in a cylindrical casing 2 which may be a nozzle or any other member having an inlet and outlet and a cylindrical interior. The body 1 is hollow and provided with a chamber 3 that communicates with recesses 4 formed by hollow arms 5. In the form of my invention shown in the drawing these arms are arranged in cross fashion and communicate with each other and each is provided with an outlet 6. Attention is called to the fact that each outlet 6 is arranged in such a position that the liquidtherefrom will strike the interior surface of the casing 2 at a tangent thereb g ving a whirling action to the liquid. t Wlll be noted that when the element is arranged in the casing, individual pockets 7 W111 beprovided adjacent the outlets 6 so that the issuingrliquid may have the proper movement. 7

As far as I have proceeded it will be seen that I provide an'element of such a construction and outline that the same may be read- 11y cast and willfreely deliver from the mold with the additional advantage that absolute accuracy in forming the element is not necessary as excess metal may be readily removed and the outlets drilled in the propenposltion. A very important feature of my invention is that the outlet 6 may be of any size thus regulating the capacity of the liquid discharge of the element.

If found advantageous in practice my element may be constructed to provide two or more streams of different characteristics and for this purpose I have shown in Fig. 4 the element additionally provided with an axially arranged opening 8 whereby a straight jet of water is provided acting in conjunction with whirling streams issuing from the outlets 6. If found advantageous in practice each projection may have its surface adjacent an opening'6 curved as shown at 9, Fig. 5, so as to give a larger capacity to the pocket 7.

From the foregoing description taken in connection with the accompanying drawing it should be apparent that I provide a device of simple substantial inexpensive construction that may be manufactured in large quantities at a relatively low cost.

Having described my invention, what I claim is:

1. In spray means, a cylindrical casing, a hollow body fitting snugly within the casing and provided at its upper end with a hollow multiple armed projection in direct communication with the interior of the body, the arms of said projection being each provided in one lateral wall with a discharge opening, the openings of the arms being similarly directed and the opening of each arm being disposed to discharge in substantial parallelism with the succeeding arm.

2. In. spray means, a cylindrical casing, a hollow body fitting snugly within said casing and open at its lower end, said body low cruciform projection the arms of which are in direct communication with the interior of the body, each of said arms being provided in one of its lateral wallswith a discharge opening and all of said openings being similarly directed. Y

3. In spray means,- a cylindrical casing, a member comprising a hollow body open atits lower end'and having, a hollowv cruciform projection extending from the upper end of the body and indirect communication with the interior thereof, said member. fitting snugly within the casing and the arms of said projection being each provided with a discharge opening through one lat eral wall positioned above and disposed to discharge parallel with the top of the body, all of said openings beingv similarly directed, j a

4'. In spray means av cylindrical casing,

a hollow body fitting snugly within the easing and provided at its upper end with a hollow cruciform projection in direct communication with the interior of the body, each arm or said projection being provided in one lateral wall with a circular discharge opening positioned above the body, said openings being similarly directed.

5. A spray element comprising .a hollow body adapted to fit snugly within a cylindrical casing of a spray nozzle, said body being open at its lower end and provided at its upper end with a hollow cruciform projection the arms of which are in direct communication with the interior of said body, each of said arms being provided in one lateral wall with a discharge opening, said openings being similarly directed.

In testimony whereof I afiix my signature.
